APPARATUS FOR HANDLING HAY, &c.

Specification of Letters Patent.

Patented .Tune 23, 1908.

Application filed October 31, 1907. Serial No. 400,085.

To all whom it may concern.'

Be it known that I, CLARENCE W. WOOD, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented a new anduseful Apparatus for Handling Hay, &c., of which the 'following is a specification.

This invention has relation to apparatus for handling hay, manure etc., and it consists'in the novel construction and arrangement of its parts as hereinafter shown and described.

The object of the invention is to provide an apparatus of the character indicated which is adapted to be easily and readily o erated for elevating the material and depositing the same upon a stack or upon vehicles as desired.

The power for operating the apparatus is preferably applied through a rotatable sweep adapted to be moved by draft animals although other means such as an engine may be employed if desired.

The apparatus consists primarily of a frame upon which is mounted a revoluble derrick which is operatively connected with an operating means and which is rovided with a swinging boom also connecte with an operating means. The sweep or engine is also mounted upon the said frame and is so arranged as to transmit movement to the said operating means when desired` Figure 1 is a side elevation of the apparatus. Fig. 2 is a top plan view of the same and, Fig. 3 is a erspective view of boom support plates use( in the apparatus. y l

The apparatus consists `of the `frame or platform 1 upon one end of which is mounted an annular track 2 having at its center a tubular pintle 3. The derrick consists of a circular base 4 mounted upon the wheels 5 which travel upon the track 2. Said base is provided at its center with a bearing 6 which is journaled upon the pintle 3. The beams 7 are mounted at their lower ends upon the base 4 to one side of the center thereof and are su ported in inclined position upon the saic base by means of the braces 8. The said beams 7 are spaced apart and support at their upper ends a pulley 9. At points substantially midway between the ends of the said beams and upon the inner sides thereof are attached the triangular plates 10 and the rollers 11 are journaled for rotation between the said plates. The boom 12 is mounted between the beams 7 and is to engage a spring actuated catch 19 mounted upon the boom. One end of the line 19 is attached to the catch 18 and the said line may be pulled by an operator whereby the catch 18 is disengaged from the shank 17 which will permit the fork 16 to tilt upon its pivotal support.

As illustrated in the accompanying drawing the means for supplying movement to the f' movable parts of the derrick consists of a sweep 20 which is fixed to a vertically disff posed shaft 21. The beveled gear wheel 22 is also fixed to the shaft 21 and the said shaft 21 is journaled for rotation upon the frame or platform 1. The bearings 23 are also mounted upon the frame or platform 1 and the horizontally disposed shaft 24 is j ournaled for rotation in the bearings 23. The shaft 24 is provided at its outer ends with a beveled pinion 25 which is in mesh with the beveled gear wheel 22. The bearings 23 are three in number and upon the side of each is journaled for rotation a winding drum designated as 26, 27 and 28 respectively. Each of the said drums is provided at its inner ends with a beveled gear wheel 29 while the beveled gear wheels 30 are loosely mounted upon the shaft 24 and are in mesh with the beveled gear wheels 29. The gear wheels 30 are provided at their hubs with clutch members 31 while the clutch members 32 are slidably mounted upon the shaft 24 and rotate with the same. In connection with the beveled gear wheel 29 mounted upon the drum 26 there is but a single gear wheel 30 while in connection with the beveled gear wheels 29 mounted upon the drums 27 and 28 there are two gear wheels 30 for each gear wheel 29 and the said gear wheels 30 are located at the opposite sides of the respective gear Wheels 29 with which they are associated so that the the frame or platform 1 and are connected at their upper ends with the clutch members 32, each said lever having contact with a single clutch member. That lever 33 which is in engagement .with the clutch member 32 adapted to be used for positively turning the drum 26 is pivotally connected to a rod 34 which in turn is pivotally connected to a rocker 35 mounted upon the frame or platform 1. The lower end of the rod 36 is also connected to said rocker 35 and the upper end of the rod 36 is connected to a lever 37 which is mounted upon a platform 38 sup-v ported above the frame 1 and to which is attached an operators seat 39. The remaining levers 33 are connected in a similar manner to similar rods 34, rockers 35, rods 36 and levers 37 with the exception that two levers 33 are connected to each rod 34. The levers 33 that are located upon the same rod 34 have contact with the clutch members 32 lying upon the opposite sides of the drums 27 and 28. Consequently when the levers 37 are in vertical positions none of the drums 26, 27 or 28 will rotate but when one ofthe levers 37 is swung toward the derrick one of the clutch members 32 will be moved longitudinally of the shaft 24 to cause either the drum 26, 27 or 28 to rotate in one direction While if the same lever 37 (provided it is one of the levers for operating the drums 27 and 28) is moved in the opposite direction either of the drums 27 or 28 will rotate in the oppo-l site direction. 1n other words, the lever 37 which is designed to operate the drum 26 is intended to be moved in one direction only while the levers 37 which are designed to operate the drums 27 and 28 are intended to be moved to one side or the other of a vertical position and are intended to so couple up the parts that the said drums 27 and 28 may be positively rotated in either of two directions. The drums 27 and 28 are provided with friction brakes 40 which are operatively connected with the treadle levers 41 mounted upon the platform 38. versely wound upon the drum 28 and pass around the base 4 of the derrick in opposite direction and are iiXed at their ends to the said base 4. Consequently by causing the drum 28 to rotate in one direction as above described one cable 42 will be wound upon while the other cable 42 will be paid out from the drum so that the base 4 will be rotated upon its aXis in one direction. By causing the drum 28 to rotate in the opposite direction the operation last above described will be reversed. Thus, means is provided for turning the derrick horizontally to one side or the other as desired.

The tackles 43 are reversely wound upon The cables 42 are reopposite end of the boom 12 Consequently, as the drum 27 is rotatedone of the cables 43 is wound thereon so that the other cable 43 is paid out therefrom, consequently, the

boom 12 will be moved longitudinally and the direction in which it is moved depends upon the direction in which the drumv 27 is caused to rotate. The cable 45 is wound upon the drum 26 and passes through the `pintle 3 up over the pulley 9 Vat the upper ends of the beams 7 down under the pulley 13 journaled at the end of the boom 12 and up to the upper ends ofthe beams 7 Where it is fixed. As the drum 26 is rotated the cable 35 is wound thereon so that the end of the boom 12 to which the fork 16 is attached `may be raised. The said end of the said 4boom is lowered by gravity.

1n starting the operation of the apparatus the operator assumes position in the seat 39 and starts the draft animal attached to the sweep 20. He then throws the center lever 37 toward the derrick wh-ich causes (through the connections above described) the drum Y 27 to rotate. This operates upon the tackle mentality of a treadle lever 41 and its connection. The lever 37 which is connected with the operating parts of the drum 26 is then swung toward the derrick and the said drum is caused to rotate which winds the tackle 45 thereon and elevates the fork 16 `with the material thereon from the ground.

When the material is sui'liciently elevated the drum 28 is caused to rotate through its lever 37 and the derrick is swung around as above `described so that the load upon the fork 16 may be carried over a` stack or wagon body. As soon as the load arrives at the desired point the line 19 is pulled which disengages the catch 18 from the shank 15 of the fork 16 which permits the said fork to. swing upon its supporting pivot and drop the load. Shoul the lload be elevated sufliciently be-V fore it is swung around above the oint at which it is desired to be dropped the ever 37 which is connected with the means for operating the drum 26 should be thrownback to a vertical position and the brake 40 applied tothe drum 2-7 whereby the load will be held in mid air while it is being swung laterally. The parts in the apparatus are so arranged that the movements above described may besimultaneously accomplished or successively brought about in any desired order. l

Having described my invention, what I i claim as new and desire to secure by Letters.

Patent is 1. In an apparatus as described, a derrick comprising a rotatable base, a beam erected thereon, a boom mounted upon the beam and ada ted to move longitudinally with relation t Iereto7 a fork pivotally attached to the boom a primary moving means and means for transmitting movement from the iirst said means to the derrick to turn the same, to the boom for moving the same longitudinally and to the boomfor raising and lowering the same.
